	* For card combos where the decoder is on the PCI bus (Conexant Blackbird, Philips Empress, ATI Theatre, etc.), you can grab either the raw video or the compressed (MPEG2) video. These cards register two devices, one for raw video (/dev/video0) and one for compressed (/dev/video1). For this to work you will need the [http://ivtvdriver.org/ IVTV] firmware.		* For card combos where the decoder is on the PCI bus (Conexant Blackbird, Philips Empress, ATI Theatre, etc.), you can grab either the raw video or the compressed (MPEG2) video.
